THOMAS W. H. MOSELEY AND VICTOR KOCH, 0F SGRANTON, PA.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 225,629, dated March 16, 1880. Applica-tion led August 6, 1879.

To all whom it may concern Be it known that We, THOMAS IV. H. MOSE- LEY and VICTOR Kool-r, of Scranton, in the county of Lackavvanna and State of Pennsylvania, have invented a new and useful Improvement in Refrigerators, ot' which the following is a specification.

Our invention relates to a refrigerator made up of corrugated sheet-metal plates connected in pairs With the corrugations at right angles to each other, as described in Letters Patent No. 204,445, granted, June 4, 1878, to T. W. H. Moseley for a steam-radiator.

Our improvement consists, tirst, in the combination of two crossed corrugated plates and a vertically-corrugated inner plate or sheet.

Our improvements also consist, in a refrigerator, of the three sheets or plates, one or more of them corrugated, as4 described, and forming two spaces or chambers, the outer one of which is packed with non-conducting material, and the inner one of which is employed for the circulation of air, Water, or vapor, as set forth.

Our improvements also consist in the combination of a corrugated sheet-metal shell and a surrounding WoodenV frame-Work.

In order that our invention may be fully understood, We will proceed to describe it with reference to the accompanying drawings, in Which- Figure l is a horizontal section of our improved refrigerator. Fig. 2 is a vertical section on the line 2 2, Figs. l and 3. Fig. 3 is a vertical section on the line 3 3, Fig. 2.

In carrying out our invention, We construct a box with its four sides, top, and bottom made up of six of the s'team-heat radiators described in patent of Thos. W. H. Moseley,

No. 204,445,J une 4, 1878, which consist each of two corrugated metal sheets, l 2, united to each other, with their corrugations running across or at right angles to each other, these sheets being surrounded at their ends and edges by metal frames or flanges, making the points of union of frame and sheets air, steam, and Water proof. Five of these radiators, A B C D E, are united at their inner edges to produce the open box. Beneath the lower edges of the four sides, A B C D, and covering the bottom E of the box, We apply a flat sheet, E3, which makes the third sheet, hereinafter named, for the bottom member of the box, besides passing' entirely under all the sides, thoroughly uniting all of these live members. and making them one whole or complete body. The sixth member or radiator, F, is to be used as a lid or door, and united to the others and adapted to do the Work of a lid or door by hinges H, confining it to its use and union with the other iive members.

To complete the structure for an efficient refrigerator we use and attach tothe inner sides of these radiators a third sheet, 3, the

four sides for the box being so arranged as to have the outer sheet, l, with its corrugations vertical, the next or middle sheet, 2, With its corrugations horizontal, and the third or inner sheet, 3, vertical, thus producing two distinct spaces or cham bers. The outer spaces between the plates l 2 being air-tight, we ill with marble, coal, or coke dust, coal-ashes, and plasterof-paris, equal parts of each, Well mixed dry, and then, in very thin slush or mortar, fill the exterior space with this. The inner chamber, between the plates 2 3, we 'also fill With cement or marble, charcoal, or coke dust, dry.

Our object is to keep th'e outside packing as solid and compact as possible, for the purpose of securing the best non-conducting qualities of the packing that is possible to attain to prevent the heat penetrating to the inner chambers and main chamber or cavity of the refrigerator. The inner packing, being left loose, composed as it is of porous cooling substances, is intended to admit the air and water freely from the inside of the refrigerator at its bottom through orifices in the side sheets for that purpose, and by the capillary attraction of these substances all Water in the bottom of the refrigerator is drawn up to keep the main chamber not only cool but comparatively dry.

When the refrigerator is to be used for purposes where so 10W a temperature is `not required, and a greater current and quantity of air may be needed and used, We apply an uncorrugated sheet on the inner side or for the third sheet, and Wholly omit the absorbent or capillary packing, and We may omit the water on the main tloor or bottom ofthe refrigerator. Perforations are provided at the bottoms of these inner sheets to admit Water and air, also IOO in the corrugated sheets with the capillary absorbent packing, also at top of both classes of sheets to allow the escape of any surplus or rareed air.

The bottom of the refrigerator we do not corrugate, needing a plain smooth surface for the general distribution of the water into the orifices in the bottoms of the four side sheets. The vapor arising from water in the capillary chamber passes off through grooves 4L at top and through the wooden frame-work G.

We deem it necessary that the inner packing should be kept constantly suppliedwith water, and (as our invention nearly or entirely dispenses with the need of ice) in case water is not supplied from the melting of ice we sup ply the same from time to time. rlhis flood of water is not only intended for keeping theca pillary chambers supplied with water, but effeetually prevents the intrusion of insects.

We believe it desirable to have at all times from one-eighth to one-quarter of an inch of water on the bottom of the refrigerator and no more; and to regulate this we place a small waste-pipe, WV, in one corner or at one side of the bottom of the refrigerator main chamber, which is intended not only to act as a Weir or waste-pipe, but the principal inlet of air to the main chamber. The box having been thus com pleted, we surround it at top, bottom, and corners with a neat and substantial frame, G, of wood, tting closely all the corners or angles produced by the peculiar way of uniting the siX radiators to form the box for our refrigerator.

We make our openings or doors mostly at the top, to be lifted or counterpoised by Weights through ropes and pulleys. The doors 'are hinged to the wooden frame-work by the aid of a board united to the radiator used as a door or covering.

The whole thus constructed makes an attractive and effective refrigerator of great strength, durability, and economy.

Having thus described our invention, the following is what We claim as new and desire to secure by Letters Patent:

l. The combination ofthe crossed corrugated plates 1 2 and the inner plate or sheet, 3, substantially as and for the purposes set forth.

2. In a refrigerator, the combination of the plates l 2 3, one or more of them corrugated, as described, and forming two spaces or chambers, the outer one of which is packed with non-conducting material, and the inner one of which is employed for the circulation of air, water, or vapor, as set forth.

3. The combination of the corrugated sheetmetal shell and the surrounding frame G, as herein set forth.
